POSITIVE WATER ME TER.

Specification of Letters Patent.

To all v'whom it may concern:

Be itknown that I, EDMUND JAMEs FRYER, asubject ofthe King of GreatBritain, residing atl Claremont, in the State of Vestern Australia andCommonwealth of Australia, have invented certain new and usefulImprovements in Positive Water-Meters, of which the following is aspecification.

This inventionrelates topositive water meters and in this meter themeasuring ofthe Water is effected in a displacement and replacementmanner by a tight fitting and double action blade which partiallyrotates on a vertical axis or pivot within the measuring'chamber andsaid blade automatically measures a determinate volume both on itsforward and return travel within said chamber and forwhich purpose theunmeasured water is fed on to either face of the blade.

The meter is comprised-of a water reception, a measuring and a dischargechamber,

the latter of a V section While the controlling valve and operativemechanism except the `the right hand inlet port open.

blade are containedk within the reception chamber, upon which later issuperimposed the dial and registering mechanism.

In order that the construction and operation of the meter'may be clearlyunderstood the same will be explained with the aid of the attacheddrawings in which Figure 1 is a sectional elevation ofthe meter. Fig. 2is a sectional plan on line 1 2 of Fig. 1. Fig. 3 is a plan on line 3 4of Fig. 1 with the meter cover removed andishowing Fig. 4 is a plan online 3 4 of Fig. 1 the meter cover eing removed and the left hand inletport open and the flange of the measuring chamber not shown. Fig. 5 is apart sectional elevation on line 5 6 of Fig. 3 and looking from theyleft in the direction of the arrow. Fig. 6 is an underside plan of theslide valve.

In these drawings and particularly as shown in Fig. 1 (L is the waterreception chamber-into which the unmeasured water enters by the inletfeed pipe al, while b is the measuring chamberv into which theunineasured wateris led by the right and left hand ports b1 and b2, andb3 is the outlet port for leading the measured water into the chamber b4which is of a V section and inclosed within the measuring chamber (seeFig.'2), and from said chamber btthe measured water is discharged'andled to the consumer by the out` let pipe b5. The reception chamber d and'the chamber b4 through the portA b3.

the measuring chamber are connected together by the flanges and boltst6.

The clock work or registering mechanism which may be of any approvedtype is contained in the casing c which is superimposed: pn thereception chamber a and as shown Ain The meter is self operated by theblade d which has oscillating operating movement within the measuringchamber b and between any approved limit points as X X1 as shown in Fig. 2.and which travel is governed by the number of teeth on thequadrant hereafter referred to. This' blade gives initial movement tothe meter and is mounted on the vertical axial spindle d1 working inbearings formed in the top and bottom plates d2 and d3 said spindlebeing provided with the nut d4. This pivot spindle d1 at its upper endcarries the pinion e which inter'- gears with the internally toothedquadrant e1 said quadrant oscillating within the water reception chambera and being connected yat its eye c2 to the pivot e3, said pivot beingsecured to the top plate d? and as clearly shown in Fig. 1.

Motion may be imparted to the registering mechanism by means of a pinionand studf which is attached to the ivot e3 but said means form no partof this invention as same may be of any approved type or form.

To the eye e2 of the quadrant is secured one end of a flexible arm gwhich at its other end g1 is secured to the slide valve g2 for operatinglthat is both as inlet and outlet ports, so that when the unmeasuredwater is entering the measuring chamber b through the port b1 or seen atU in Fig. 5 the measured water on the reverse side of the blade d isescaping from; said chamber through the port?)2 and irlto T isslidevalve is formed with the double pointedV extension h which on itsunderside carries -thel locking pins h1 and said pins engage lalter'-nately against the inner and outer faces of the gapped and upstandingridge h2 formed on the quadrant @leso giving an intermittent lock andrelease action to the valve g2 and upon their release through the gapsimpart an instantaneous escapement movement to the valve g2, saidrelease being urged by the flexible arm g.

The operation of my positive meter is chiefly as follows-Let it beassumed that the right hand inlet port b1 of the measuring chamber isopen and that the blade d is in the dotted position and all as shown inFig. 3. rlhe unmeasured water `enters the reception chamber a by thefeed pipe al and passes as denoted by the arrow U through such openinlet port b1 into the measuring` chamber, (see Fig. 5) whereupon by thepressure of the water the blade d is ycaused to move from the point a;until it reaches its other limit point ci as shown in Fig. 2 suchmovement being controlled by the number of teeth on the quadrant el andconsequently the volume of water that is 4measured depends on the degreeof movement of the blade d. l/Vhile the port b1 is uncovered and wateris entering the chamber b therethrough to act on one side of said blade,the water on the other side of the blade is issuing from the chamber b,through the port b2 valve cavity gri and port b3 into the chamber b4 asseen at M in Fig. 5, the Water discharging from said chamber b4 throughthe pipe b5. lt is obvious that the l quadrant el by means of the pinione moves in companionship with the blade d while the flexible arm g in apunctual and intermittent manner operates the slide valve g which lattermoves radially on its pivot g3. The purpose of the pins h1 is to opposethe action of said arm g so that the valve gr2 is retained in positionuntil suddenly released by the pins h1 escaping through the gaps of theridge h2 on the quadrant el. rl`his resistance or non-movement of thevalve causes the flexible arm to sag as seen in Fig. 4 and upon theescape of the pins as above mentioned the arm by its resiliency assertsitself and assumes a straight position so causingthe sudden and punctualrelease of the valve and the instantaneous covering of either of theports lil or b2 through which the measured water escapes from thechamber b. The volume of measured water is at same time registered bythe clock work which as before stated is operated by the stud and pinionf connected to the pivot c3 of the quadrant. Concurrently with thecovering of either of the ports b1 or b2 the same action of the valvesuddenly uncovers the companion inlet port and allows a fresh supply ofunmeasured Water to be fed on to the reverse side of the blade d soAthat the measuring operation is repeated in a reversed direction andconsequently another volume of water isregisdischarge chamber and withan outlet opening communicating with the discharge chamber, a blademounted for oscillating movement in the measuring chamber, a shaftcarrying the blade and projecting beyond the top wall, a pinion on theprojecting end of the shaft, a pivotally mounted segment on the topwall, said segment having teeth meshing with said pinion, a valvepivotally mounted on the top wall and havinga chambered under faceproportioned to cover said outlet port and either of said inlet portsand an operative connection between said segment and said valve foroperating the latter from the former.
